Abstract

Jalan merupakan salah satu bentuk sistem transportasi darat yang menghubungkan daerah yang satu dengan daerah lainnya. Perkerasan lentur yang umum digunakan berupa perkerasan dengan campuran Aspal Concrete (AC) yang didasarkan pada AASHTO yang memiliki lapisan structural antara lain AC-WC, AC-BC, dan AC-Base. Penilitian ini menggunakan metode eksperimental dengan bahan tambah pasir pantai alam indah Kota Tegal sebagai pengganti sejumlah agregat halus dengan kadar 25%, 50% , dan 100%. Nilai yang didapat yaitu meliputi nilai kepadatan pada kadar 25% sebesar 2,141 gr/cc, kadar 50% sebesar 2,130 gr/cc, Dan kadar 100% sebesar 2,128 gr/cc. VIM pada kadar 25% sebesar 11,27%, kadar 50% sebesar 11,73%. Dan kadar 100% sebesar 10,32%, VMA pada kadar 25% sebesar 21,36%, kadar 50% sebesar 21,76%, Dan kadar 100% sebesar 21,53%., VFA pada kadar 25% sebesar 47,22%, kadar 50% sebesar 46,09%. Dan kadar 100% sebesar 52,06%. stabilitas pada kadar 25% sebesar 1178,76 kg, kadar 50% sebesar 961,62 kg, Dan kadar 100% sebesar 878,90 kg., kelelehan (flow) pada kadar 25% sebesar 3,68mm, kadar 50% sebesar 4,51mm, Dan pada kadar 100% sebesar 5,86 mm., dan marshall quotient pada kadar 25% sebesar 320,31 kg/mm, kadar 50% sebesar 213,2 kg/mm, Dan kadar 100% sebesar 151,01 kg/mm.

Abstract

Population growth and increasing economic activities have raised the demand for durable and high-quality road infrastructure. However, the Asphalt Concrete–Wearing Course (AC-WC), which functions as the surface layer of flexible pavements, often suffers from premature damage such as cracking and deformation due to heavy traffic loads and extreme weather. Therefore, improvements in asphalt mixture materials are necessary. One alternative is the use of liquid latex derived from natural rubber as an additive. Owing to its high elasticity, liquid latex is expected to improve flexibility, crack resistance, and durability of asphalt mixtures. This study aims to evaluate the effect of liquid latex addition on the Marshall characteristics of AC-WC mixtures and to determine the optimum latex content. The research employed laboratory experimental methods using liquid latex contents of 0%, 2.5%, 5%, 7.5%, and 10%, with three specimens prepared for each variation. The evaluated parameters included stability, flow, air voids in the mix (VIM), voids in mineral aggregate (VMA), voids filled with asphalt (VFA), Marshall Quotient (MQ), and density. The results indicate that liquid latex significantly affects all Marshall parameters. However, excessive latex content reduces mixture performance. The optimum condition was achieved at 2.5% liquid latex with an asphalt content of 5.65%, producing a stability of 1102.2 kg, flow of 3.13 mm, VIM of 3.87%, VMA of 17.01%, VFA of 77.26%, MQ of 355.15 kg/mm, and density of 2.297 g/cc. All parameters satisfy the 2018 Bina Marga General Specifications (Revision 2).
