Abstract

Evaluation of correlations regression between functional condition roads and structural condition of the pavement needs to be implemented, a result of condition handling the maintenance of roads in the province of South Sulawesi and South Kalimantan are still less accurate because the determination of handling is only determined from one of the condition steadiness of road, Data used to facilitate this research is secondary to data obtained in 2014, in which secondary data obtained from Balai Besar Pelaksanaan Jalan Nasional (BBPJN) and Balai Pelaksanaan Jalan Nasional (BPJN). Flexible pavement conditions on the roads of research in South Kalimantan Province, shows the surface roughness (IRI) has a the level of correlation conditions that reasonably represen the  elastic modulus of surface layer (E1), but the surface roughness (IRI) has a level of correlation that less represents the  elastic modulus of base layer (E2 ), while a different result is also shown by the surface roughness (IRI) can not represent the  elastic modulus of subbase layer (E3) and the  elastic modulus of subgrade layer (E4). While the condition of pavement flexible on the roads of research in South Sulawesi province, shows the surface roughness (IRI) has a level of correlation conditions that already represents the elastic modulus of surface layer (E1), but the surface roughness (IRI) has a level of correlation that reasonably represents the elastic modulus of base layer ( E2), while a different result is also shown by the surface roughness (IRI) is less representative of the elastic modulus of subbase layer (E3) and the elastic modulus of subgrade layer (E4). The difference correlation of regression relationship model’s between the functional conditions and the structural conditions for all the roads, indicated the influence of the type of pavement layers and pavement layer thickness all layer of of pavement for all the roads.

Abstract

In the construction project, especially the roads in Yogyakarta and surrounding areas, the aggregate used is derived from the Clereng Kulonprogo. This amount of aggregate usage results in scarcity and affects the price to become expensive. The use of coarse aggregate materials as an alternative is rare. In reality, it is necessary to make innovation by utilizing the coarse aggregate of zeolite stone, which is still quite widely available in the Klaten area. Based on the preliminary test, the zeolite aggregate has a lower abrasion resistance compared to the andesite aggregate from Clereng. Using a modified asphalt Starbit E-60, which has a deficient penetration value, is expected to provide better stability to compensate for the weakness of zeolite stones. A combination of a mixture between a coarse aggregate of zeolite Stones and Andesite is tested until how large the proportion of zeolite stones of such combinations can provide the optimum value to AC-BC layer pavement. This research compares the performance of the AC-BC mixture using zeolite and andesite stones. It determines the feasibility of zeolite's stone, in substituting the andesite stone, in the AC-BC mixture. It is also to know the influence of the use of Starbit E-60 in the AC-BC mixture. The comparison of those performances was referred to as Marshall characteristics, Indirect Tensile Strength (ITS), and Immersion; using Pen asphalt Pen. 60/70 and Starbit E-60 as a binder. Trial mix was applied to the bitumen content variation of 5%, 5.5%, 6%, 6.5%, to determine Optimum Bitumen Content (OBC) by conducting Marshall testing. The variety of substitution zeolite proportions of 0%, 25%, and 75% was made in each trial mix above. The research result showed that the maximum percentage of zeolite aggregate in the mixture using an asphalt Pen 60/70, which meets with specification standard, is 28%, while the mixture using Starbit E-60 is 26%. ITS value decreases as the percentage of zeolite are increased. ITS value of mix with Starbit E-60 is higher than that of mix with asphalt Pen 60/70. Cantabro Loss value increases with zeolite proportion increase, for both mixed with Starbit E-60 and asphalt Pen 60/70. Cantabro loss of mix with Starbit E-60 is lower than that of with asphalt Pen 60/70. IRS value decrease with an increasing proportion of zeolite.

Abstract

Porous asphalt is an asphalt mixture with high porosity to reduce the potential waterlogging and increase the roughness of the road surface. However, porous asphalt mixture has shortcomings in terms of strength and durability. This paper presents laboratory testing results of the effect of adding Rediset LQ-1106 additive on the performance of a porous asphalt mixture. The research was started with the determination of the optimum asphalt content. Then, the test object was made with Rediset LQ-1106 using variations in 0%, 1%, 2%, and 3% of the optimum asphalt content and carried out the Marshall test, Immersion Test, Indirect Tensile Strength, Tensile Strength Ratio, and Wheel Tracking. The test results show that adding 1% of Rediset LQ-1106 resulted in the optimum performance of porous asphalt compared to other grade additions. This performance is evidenced by the increase in the mixture stability value by 18.62%, the Indirect Tensile Strength value of 20.14%, the dynamic stability value of 35.88%, and the most negligible deformation speed compared to porous asphalt, which does not use Rediset LQ-1106. However, the Index Retained Strength, and Tensile Strength Ratio tests did not significantly increase performance.

Abstract

Pavement earlier damage in Indonesia was generally due to overloading, repetition of traffic loading, and climatic change. To overcome these main factors, the quality of asphaltic concrete need to be improved properly. This research was to know the effect of difference aggregate gradation types on pavement performance using modification bitumen of Starbit E-55 and bitumen Penetration 60/70. Research was conducted in four stages: 1) to determine optimum bitumen content of four mixture types, 2) Marshall standard and immersion tests at each bitumen content of the mixtures, 3) indirect tensile strength test, and 4) analyzing and comparing the results. The research result shows that bitumen starbit E-55 can be used as an alternative binder for asphaltic concrete. The optimum bitumen content of bitumen Starbit E-55 in AC-WC was 5.75% for dense graded and 6.2 % for gap graded. The mixture with bitumen Starbit E-55 was weaker than that of bitumen penetration 60/70 for both dense and gap graded. Immersion test result shows that the index of retained strength of specimen using bitumen Starbit E-55 was more sensitive than that of using bitumen Pen 60/70. Whereas, in term of indirect tensile strength, specimens using bitumen Penetration 60/70 was more sensitive than that of specimens using Starbit E-55.
