“…The cantabro test results of the RAP+10% stone dust mixture was 9.02%, meanwhile the mixture with 20% stone dust gave 10.14%. This values are less then the recommended 16% at tropical temperature around 30°C [16]. Referring to figure 3 that is in line with figure 4, the mixture with 10% stone dust was denser, with added optimum asphalt content of 3%, has better resistance to aggregate raveling due to impact action.…”

The use of natural aggregates can be reduced by utilizing Reclaimed Asphalt Pavement (RAP). In field, there have been many simple recycling applications of RAP with addition of new asphalt and stone ash as road pavement on community housing areas. The objective of this experiment is to provide engineering properties of the mixture. Asphalt pen 60/70 was softened or rejuvenated with 11% SAE 10 engine oil, to obtain asphalt pen 180/200. The mixtures were produced by adding the RAP with 10% and 20% rock ash and soften asphalt, in hot mix process. The added asphalt content was varied by 2%, 2.5%, 3%, 3.5% and 4% by weight of the RAP, and compacted at 2x50 Marshall blows. The mixture of RAP with 10% stone ash at 3% added asphalt gave better performances compared to the mixture with 20% stone ash, in which the stability value was 3380.5 kg, flow 3.08 mm, Marshall Quotient of 1097.65 kg/mm, VIM 3.077%, VMA 18.95%, VFB 83.84%, Cantabro 9.02%, ITSM 5422 MPa, creep slope 0.267, and fatigue with load of 700; 900; 1100 KPa failed at 6101; 1471; 831 load repetitions. The mixture well meet the specification for typical mixtures for low to medium trafficked roads.

Open-graded-fraction-course (OGFC), is a hot asphalt mixture usually utilized as a private purpose wearing course, because of open graded asphalt mixture and aggregates skeleton (stone-on-stone) contact, it contain a relatively high air voids’ percentage, after compaction which are permeable to water. In this research one type of gradation was used (12.5 mm) NMAS, to preparing the OGFC asphalt mixtures, penetration grade 40/50, crushed aggregate, asphalt content prepared with 4 % and up to 6 % by weight of mixture with 0.5 % increments. Optimum asphalt content (OAC) was selected based on these criteria, air voids content, asphalt draindown, permeability, and abrasion resistance (aged and un-aged) condition. The mix performance had been investigated by indirect tensile strength and moisture susceptibility (sensitivity) measured according to the (AASHTO T283-14). Results illustrate that the increasing of asphalt binder content leads to a decrease of the air voids content, abrasion loss and permeability values, while draindown increase, conversely, the indirect tensile strength (ITS) had been significantly increased for both conditions and this is a gaod suggestion to resistance alongside moisture susceptibility. It can be decided that the increasing of asphalt binder percent in OGFC asphalt mixture, leads to an increase in the thickness of binder coating around the aggregates. On the other hand, the influence of modifier that prepared with 4% styrene-butadiene-styrene (SBS) on OGFC asphalt mixture tends to improve the mix properties and exhibit higher (TSR) as compared with original asphalt by (31, 27.7 and 24.4) % at asphalt percent (4.8, 5.3 and 5.8) %, respectively. The SBS improved the adhesion between aggregate and asphalt which leads to reduce stripping of HMA, horizontal deformation, and increased the tensile stiffness modulus value.

Preparation of double layered specimen at laboratory scale is important in evaluating the performance of bond strength between pavement layers since it is normally less costly. It however involved single face compaction at wearing course layer during the specimen preparation which raised potential skepticism over the quality of the layer compacted at single face only. This paper presents the properties of single face compacted porous asphalt (SFCPA) specimen compared to conventional double face compacted porous asphalt (DFCPA) specimen. These specimens were of Grading A in accordance with the specification from Malaysia Public Works Department (PWD). The permeability and abrasive loss were investigated for specimens fabricated at 3 thicknesses of 35mm, 50mm and 65mm at an allowable limit of ±1mm. 50 blows compaction at each face according to PWD specification is adopted for DFCPA specimen, which resulted in compacting effort of 100 blows compaction for SFCPA specimen was applied for every thickness. For both tests, SFCPA possessed lower permeability and abrasive losses compared to DFCPA. This observation is the consequences of potential aggregate crushing in SFCPA which then partly filled up the voids within the specimen and reducing the permeability. Increased in density as a result of permeability reduction had increased the interlocking between coated aggregate particles, hence the abrasive loss in SFCPA is lessened.
