Modifikasi Resipren dan Bitumen dalam Peningkatan Kekuatan Aspal telah dilakukan. Aspal modifier dibuat dalam 7 jenis variasi perbandingan aspal, bitumen, dengan resipren yang telah dilarutkan dengan toluene sebesar 75:20:5 ; 70:20:10 ; 65:20:15 ; 60:20:20 ; 55:20:25 (v/v/b) dalam 100 mL, penambahan agregat pasir halus 300 gram dan agregat kasar kerikil 50 gram, dan diproses dalam ekstruder pada suhu 150oC. Sifat mekanik dan sifat termal aspal modifier yang diuji meliputi kuat tekan, daya serap air, morfologi dengan TEM. Hasil karakterisasi menunjukkan bahwa campuran aspal, bitumen, dan resipren dengan perbandingan 55 : 20 : 25 efektif dalam meningkatkan sifat mekanis dari campuran aspal dimana dihasilkan kekuatan tekan maksimum sebesar 0,974 mPa. Sifat fisik menghasilkan penyerapan air sebesar 0,63%. Hasil uji morfologi dengan TEM memperlihatkan adanya perbedaan setelah bitumen ditambahkan kedalam campuran aspal dan resipren. Recipient and bitumen modifications in asphalt strengthening had been carried out. Asphalt modifier was made in 7 types of comparison of asphalt, bitumen variation, with recipient (dissolved with toluene by 75: 20: 5; 70:20:10; 65:20:15; 60:20:20; 55:20:25 (v/v/b) in 100 mL), 300 grams of fine sand aggregate and 50 grams of coarse gravel aggregate; then processed in an extruder at 150oC. The mechanical properties and thermal properties of the modifier test included compressive strength, water absorption, and morphology with TEM. The characterization results showed that asphalt, bitumen and recipient mixtures with a ratio of 55: 20: 25 were effective in increasing the mechanical properties of the asphalt mixture where the maximum compressive strength was 0.974 mPa. Physical properties produced water absorption of 0.63%. The results of morphological tests with TEM showed that there was a difference after bitumen was added to the asphalt and recipient mixture.
