“…Pada standar nasional Indonesia untuk perkerasan jalan aspal yang dikenal dengan nama standar Bina Marga 2018, perbedaan temperatur produksi ini ditetapkan sebesar 30℃ dimana WMA diproduksi pada suhu 130℃ (Dirjen Bina Marga, 2018). WMA memiliki sifat mekanis yang lebih rendah dibandingkan dengan HMA standar, seperti dalam hal ketahanan terhadap deformasi permanen (rutting), walaupun beberapa tipe aditif tertentu dapat membantu mengurangi perbedaan tersebut (Nur Naqibah Kamarudin et al, 2018;Zhao et al, 2012). Walaupun penelitian lain menunjukkan bahwa WMA menghasilkan nilai ketahanan terhadap lelah yang relatif setara dengan HMA (Piccone et al, 2020a;Sukhija & Saboo, 2021), tetapi tingkat adhesi yang rendah akibat adanya kandungan air dalam campuran menyebabkan WMA memiliki ketahanan terhadap air yang lebih rendah (Albayati et al, 2018;Rahman et al, 2021).…”

Studi ini membandingkan dampak lingkungan dari produksi campuran aspal hangat (Warm Mix Asphalt -WMA) dimodifikasi polimer EVA dengan dosis 5% berat bitumen melalui metode pencampuran kering (dry mixing) dengan campuran aspal panas (Hot Mix Asphalt -HMA) standar pada skala laboratorium menggunakan metode Life Cycle Assessment (LCA,) dengan lingkup dari akuisisi bahan baku hingga produksi di laboratorium aspal Universitas Pelita Harapan. Kajian ini menggabungkan database CML-IAMidpoint dan Eurobitume serta pengukuran emisi di laboratorium. Hasil pengukuran menunjukkan penurunan pada suhu produksi WMA menghasilkan emisi CO2 dan Volatile Organic Compound (VOC)

“…WMA's disadvantages addressed by Esenwa et al (2011) and Rashwan (2012) are mainly related to the potential to reduce material durability, and it has potential for rutting and moisture susceptibility issues [11,12]. WMA has a higher degree of compaction, which provides better workability of compaction compared to HMA mixture and the WMA mixture has a lower (Mr) than HMA mixture which could suggest that WMA mixture is more susceptible to rutting [13,14]. The resistance of the WMA-emulsified asphalt to rutting is quite remarkably less than their counterpart the HMA.…”

Development of hazardous gases emissions through the production and construction of Hot Mix Asphalt (HMA) have encouraged the transition to Warm Mix Asphalt (WMA) which is considered as one of the best choices of sustainable materials in asphalt pavement. The temperature reduction in the mixing, handling, and compaction of the mix gets in saving energy, cutting emissions and significant cuts in construction costs. In this investigation, two WMA mixtures have been prepared in the laboratory using medium curing cutback (MC-30) and cationic emulsion asphalt. HMA mixture was also prepared for comparison. Marshall size Specimens of (101.6 mm) in diameter and (63.5 mm) in height were constructed from these mixtures and subjected to repeated Indirect Tensile Strength test (ITS) to determine the effect of asphalt type and content on deformation and resilient behavior of asphalt mixture. Another group of cylindrical specimens of (101.6 mm) diameter and (101.6 mm) in height have been constructed from these mixtures and subjected to repeated compressive stresses test to determine the rutting resistance of asphalt mixture. Test results were analyzed and compared. It was concluded that, the permanent deformations for cutback and emulsion treated WMA was higher than that of HMA by (50 and 35) % respectively. The Resilient Modulus (Mr) at 25 ⁰C under repeated (ITS) for cutback and emulsion treated WMA was lower than that of HMA by (39.95 and 27.94) % respectively. On the other hand, the (Mr) for cutback and emulsion treated WMA was higher than that of HMA by (43.75 and 5.47) % respectively under repeated compression load at stress level 0.138 (MPa).
