    Abstract

    Reflection cracking is one of the main issues on the pavement in Indonesia. Reflection cracking is longitudinal cracking , transverse , diagonal or box shape on a new layer of asphalt paved describing patterns of cracks underneath . Improvements made generally cover cracks with liquid asphalt overlay before implementation . Therefore , granting a special coating to absorb the voltage at the interface between the asphalt layer is believed to inhibit the rate of development of reflection cracking . This study aims to determine the pattern of cracks , determine the relationship between the length of the crack reflection on time and to determine the effect of the strengthening SAMI views of flexural strength test ( flexural strength ) in addition SAMI conducted laboratory SAMI used wire mesh . SAMI is installed on the interface between the layers of the existing asphalt overlay layers her . Specimens made with mold 50 cm x 10 cm x 10 cm and compacted with Marshall compacter . To simulate the crack initiation in the existing layers of plywood mounted 3 mm per 10 cm distance . Furthermore test flexural strength ( flexural strength ) with load placement method using distance -third of the length of the specimen (third point loading ) to determine the ratio between the crack patterns and the development of test objects with SAMI . These observations indicate that the cracking pattern of use of a SAMI , wire mesh has a crack pattern that rises to the surface of the artificial crack is not straight on , but shifted to the right or left of the artificial crack , while the SAMI aggregate form , without SAMI constantly cracking pattern of cracks artificial . While the ability to withstand maximum load of wire mesh SAMI be able to withstand 5.7 times better than when compared with specimens without using SAMI , and 4.56 times better when compared with specimens mengguankan aggregate SAMI , It this means that the wire mesh in addition to functioning resist reflection cracking in the overlay layer also strengthening the pavement .
