Asphalt mixtures are the most widely used material for road pavement. To determine mixture quality, comprehensive laboratory testing is essential. UP. PPP provides a range of asphalt mixture tests conducted in accordance with national standards, supporting both government and private-sector construction projects across DKI Jakarta.

All testing is performed by the accredited Testing Laboratory (LP-253-IDN) under the National Accreditation Committee (KAN), consistently applying SNI ISO/IEC 17025:2017 standards. The laboratory also implements the ISO 45001:2018 Occupational Health and Safety Management System.

Asphalt testing forms a critical component of road infrastructure quality assurance, and UP. PPP Bina Marga is equipped to carry out these evaluations with precision and reliability. The Marshall Test, one of the most fundamental procedures, assesses both the stability and flow of compacted asphalt specimens, providing essential data on how a pavement mixture will perform under traffic loads. By measuring deformation resistance alongside strength, this test helps engineers determine whether a given asphalt formulation is suitable for the demands of urban road networks. Such testing is vital for ensuring that road surfaces in DKI Jakarta can withstand the stresses of daily use over many years.

Beyond the Marshall Test, asphalt content extraction is another key procedure offered by the laboratory. This test determines the exact percentage of binder present in a prepared asphalt mixture, verifying that the material matches the specifications set out in the job-mix design. Proper binder content is essential for pavement durability, as too little binder leads to cracking and raveling, while too much can cause rutting and bleeding. By confirming compliance with design standards, this analysis helps contractors and government agencies avoid costly premature failures and ensures that public funds are spent on roads that will serve the community effectively.

Sieve analysis of aggregates used in asphalt mixtures is equally important for achieving consistent pavement quality. This test evaluates the gradation of both coarse and fine aggregates, ensuring that the particle size distribution falls within the required specifications for the intended pavement layer. Proper aggregate gradation directly affects the stability, workability, and durability of the finished asphalt surface. Through these combined laboratory procedures, UP. PPP supports the overarching mission of Dinas Bina Marga to deliver safe, long-lasting road infrastructure across DKI Jakarta, helping to maintain the capital city's transportation network at a high standard of service.
