Abstract

Asphalt on pavement in long term may undergo hardening, so it needs addition of additive that can make it remain flexible. This experiment tried to produce asphalt concrete wearing course (AC-WC) using asphalt penetration 60/70 with the addition of latex, with aim to know the characteristic of AC-WC mix at the optimum of asphalt content with addition of  latex in variation of 0%, 2%, 4%, 6%, 8%, and 10% of the total binder. Latex was initially mixed with the asphalt, then the aggregates were proportioned based on ideal grading. The samples were produced in hotmix process. The density of latex was found 0.977 with dry rubber content of 61.95%. The optimum of asphalt content that was 5.7%, where all Marshall characteristics were met. It was chosen the mix with 4% latex by total binder where all properties of asphalt binder were still met. It was obtained that the Stability value  was 1439.26 kg (≥ 800 kg), Flow 3.84 mm (2-4 mm), Marshall Quotient 379.66 kg / mm (≥ 250 kg / mm), VIM  4.437% (3-5%), VMA 15.280% (≥ 15%), VFB 70.961 (≥ 65%). The mixture that contains latex had better resistance to deformation under dynamic creep loading at 40 °C.

Abstract

Patching road pothole can be done using Permanent Cold Patching (PCP). This research main aim was to analyze the characteristic of the PCP. PCP Super Cold Mix Asphalt was used for the experiment. The mixtures were compacted Marshall hummer in lab using, and plate compactor on site. It was obtained that: compaction temperature variation significantly affected the characteristic of the mixture. Compaction at 100°C and 150°C, met stability, porosity and VMA specification, but not for the VFB. It required more compaction energy. The stability of cold compacted mixture at the age of 1 hour gave 844.74 kg (min. 500 kg). Towards this value, at the age of 48 hours; 96 hours; 192 hours; 384 hours, respectively gave increase of stability of 102%; 140%; 183%; 187% and then constant. Cold compaction on site gave less performance with porosity values in a range of 4.585-8.22% (spec. 4% -10%), therefore the VFB is less than minimum 65% of VMA; the stability obtained was 1422.72 kg (>min 500kg) or 58% stability of the samples compacted in lab at the same 16 days of age where stability had become maximum (constant). Cantabro test result of the cold mix gave 100% weight loss (the sample disintegrated), meanwhile the hot mix only lost 7.56% from 16% max loss.
