Summary:Abstract The rapid development of structures so far needs to be balanced with road construction, but there are many road damages that use asphalt flexible pavements are damaged and changes or deformations in the pavement, this can be caused by the influence of heat, radiation, rainfall, volume or high traffic loads and will be overcome with the addition of natural rubber to reduce the bad things above. The research implemented.at the Road and Bridge Laboratory and the Lampung State Polytechnic Analysis Laboratory for 6 months. The treatment that will be applied in this research is the manufacture of additives with the creaming method in the Analysis Laboratory which finally concentrates latex with variations of 3%, 5% 7 and 9% of the weight of pure asphalt which will be applied with asphalt and aggregate materials. pavement to form a denser bond. Variations in making samples using the FCR (Design Mixed Formula) method or DMF design mix formula, using concentrated latex as an additive and testing using the Marshall Test testing method in road and bridge laboratories so that from the research results obtained for asphalt and latex the treatment has an effect on the value MQ (Marshall Quotient), but the interaction results show that the ANOVA table shows that asphalt, latex and the interaction between asphalt and latex show significant values. Duncan’s analysis with an alpha of 0.05 shows that the additives provide significant added value from the MQ (stability/Fatigue) kg/mm value and it is shown that the asphalt mixture with samples A and E after being mixed with additives gives a value according to the applicable standards in the table. requirement 2 for LL (traffic) Weight The min value of MQ 200 and the maximum of MQ 350 lies in a mixture of Type A 3% asphalt content and Type E with 9% asphalt content after adding latex and according to duncan’s analysis of the relationship between Asphalt Content and MQ Value. and for the best result for Flexible Pavement Industry Type A with 3% content can be recommended to be used
