Abstract

Over the past many years the well-known theory of consolidation developed by Terzaghi, directly or in extended form, has been usually applied to analyze the time rate of settlement and excess pore water pressure dissipation arising from loading a soft soil. In recent reviews, it has been observed that success in predicting magnitudes and rate of settlement using Terzaghi’s theory from different field cases ranging from excellent to poor. The anomalous behavior can be explained in terms of such factors as the non-linear relationship between void-ratio and logarithm of effective stress, and changes in permeability and compressibility as load increases. In this studys, a computer program has been developed to consider two dimensional consolidation of stratified cohesive soils under embankment loading, the theory used : i.e. 1) Terzaghi-Rendulic theory and 2) non linear theory. Three case histories were presented, i.e. Trial embankment at Juru, Malaysia, Muar Flats, Malaysia and Tickton, UK. The results indicate that predictedvalues using non-linear theory for both settlement and pore water pressure dissipation close to the field measured values comparing to those using the Terzaghi-Rendulic theory. Keywords : soft clay consolidation, non-linear theory, Terzaghi-Rendulic theory

Abstract

Nationally, Indonesia needs the asphalt materials was approximately 1.2 million tons each year and only 0.6 million tons can be provided by PT. Pertamina and the rest should be imported from another country. Meanwhile asphalt deposits are decreasing and the prices rise up following prices of world crude oil. A promising alternative to solve that problem is to use asbuton (asphalt buton) as a substitution of petroleum asphalt. In recent years, technology of asbuton have been rapidly developed, including buton granular asphalt, asbuton pre-blending and asbuton extraction. The result of full scale experiment in Kolaka, South East Sulawesi indicates that the asbuton material has the capability to substitute petroleum asphalt as well as to improve the pavement performance. Key words : asbuton, pavement performace, full scale experimental.

Abstract

RDS (Roadworks Design System) is a method to Design overlay flexible pavement and currently used by the Design and Supervison of Road and Bridge Construction (P2JJ). The method adoptic the design method which was firstly developed by DR Ray Millard. 1983 and DR Paterson. 1985. In recent years, many methods have been developed, such as AUSTROADS, 1992, Asphalt Institute MS-17, 2000 and Pusat Litbang Jalan dan Jembatan in 2005 also has released a guide to the structural design of road pavement based on deflection, Pd T-05-2005-B, 2005. From some methods mentioned above, it was found that a significant difference in the result of the overlay thickness designed. Some factors influencing are deferences in the traffic loading calculation, method in abtaining a represenative deflection (grouping an uniform deflection) and environmental factors. Principally, overlay thickness should meet two fatique criteria i.e. permanent deformation and fatique performance. Both criteria should be taken into account in calculating overlay thickness as shown in Austroads design procedure. Key words : Significant differences, Traffic volume, Deflection uniformity, Environmental factors.

Abstract

With the lack of availability of natural resources will alse affect to the road construction and maintenance process. This problem can be solved by improving the quality of material that is available near the road locations. that is the reason to implement the technologies that can improve the quality of materials which is considering some aspect namely material types, material deposits, and also the level of successful in the past. One of such technologied is the soil stabilization which is using lime and cement as the stabilizing agents. The main difference between these two kinds of stabilization is its use for a certain type of soil. The use of lime is suitable for the soils whose PI more than 10% while cement is more applicable for fine grained soils if the PI less than 10% and also for the coarse grained soils (less than 25% passing sieve No. 200). Lime stabilization will increase the bearing capacitty of soils and reduce plasticity and swelling. The succesful of road stabilization is influenced by several factors such as (i) the selection of stabilizing agent that suits to type of soils, (ii) the accuracyof mix desihn, (iii) the level of mixing and compaction in the field , and (iv) the maintenance process durig curing time.

Agregat lapis pondasi atas bawah mempunyai peranan yang penting dalam konstruksi perkerasan jalan. Untuk menjaga kualitas dari material tersebut telah dibuat persyaratan-persyaratan yang tercantum dalam Spesifikasi Lapis Pondasii Agregat. Meskipun demikian pada beberapa proyek ditemukan adanya perbedaan persyaratan yang cukup prinsipil. Untuk itu diperlukan pengetahuan yang mendalam mengenai karakteristik agregat lapis pondasi yang nantinya dipakai sebagian dasar usulan perubahan/peningkatan Spesifikasi. Usulan peningkatan/perubahan tersebut meliputi, gradasi, prosentase pecah, indeks plastistilas, prosentase agregrat halus, dan kadar air pemadatan. Gradasi lapis pondasi atas (LPA) disesuaikan dengan lengkung Fuller dan gradasi lapis pondasi bawah (LPB) diubah menjadi gradasi B1,B2, dan B3 mengacu gradasi AASHTO 1990. Prosentase pecah lapis pondasi disesuaikan dengan lalu-lintas rencana dan posisi dari pondasi tersebut. Untuk membatasi prosentase agregar halus, digunakan persyaratan PP (prosen lolos saringan 200 x PI) maksimum 25. Nilai indeks plastisitas (PI) dibatasi maksimum 6% untuk LPA dan 10% untuk LPB. Kadar air pemadatan lapis pondasi diusulkan 1% dari kadar air optimum.

Abstract

Untuk menentukan tanah dasar diperlukan teknik pengujian tegangan-tegangan dengan beban dinamis sesuai dengan beban lalu-lintas yang bersifat dinamis. Hasil yang diperoleh dinyatakan dalam modulus relisien (Mr). Parameter tersebut merupakan parameter utama dalam perencanaan tebal perkerasan secara analitis. Akan tetapi teknik pengujian teresebut memerluan peralatan yang mahal, tidak mudah dipindah-pindahkan, dan relatif susah dioperasikan. Dengan meningkatkan ketelitian pengujian dan analisa menggunakan metoda finite element, hasil pengujian CBR dapat digunakan sebagai metode alterenatif penentuan modulus relisien tanah dasar.

Abstract

Karakteristik lapis pondasi agregat umunya dinyatakan dalam suatu parameter antara lain adalh CBR dan Mr (modulus resilien). CBR dihitung berdasarkan beban statis, dan Mr dihitung berdasarkan beban dinamis, yaitu beban berulang seperti beban lalu-lintas. Mengingat pengujian yang umum dilakukan adalah CBR (emperikal) sedangkan pengujian yang mendekati kondisi lapangan adalah Mr (mekanistik), maka diperlukan pengetahuan mengenai hubungnan CBR dengan Mr. Hasil penelitisn menunjukkan bahwa hubungan CBR dengan Mr tergantung pada beban atau tegangan yang akan dipikul. Pada makalah ini disampaikan juga hasil penelitian berupa rumus persamaan untuk mwnghitng nilai Mr berdasarkan sifat-sifat fisik lainnya.

Abstract

Local material in the form of a mixture of sand and stone, including limestone is commonly found in Indonesia which at the moment generally cannot be used directly for pavement foundation because of its low quality (substandard). The use of these local materials for pavement foundation layers is very important, especially in the outermost and remote areas that do not have quality material sources as specified in specifications such as on the NTT - Timor Leste border, Trans Papua and Talaud Islands Regency North Sulawesi Province. This study aims to determine the effect of stabilization with cement to optimize the strength of the local materials. The study was carried out by experimental methods through laboratory testing. The results showed that the stabilization of the local materials with cement can produce a fairly high compressive strength value. The value of compressive strength is higher according to the increasing percentage of cement content used. Referring to the value of the compressive strength produced (in general 24-40 kg/cm2), the local material can be used for the pavement foundation layer, and for the use or application in the field, specifications are needed as recommended by this study.Key words: pavement foundation layers, substandard local material, sirtu, cement stabilization, compressive strength
