ROAD IMPROVEMENT USING RIGID PAVEMENT ON THE TARAKAN CITY ROAD
The Tarakan City Road is part of the transportation system as a service for infrastructure facilities for the impact of population growth. In order to meet these needs, new pavement planning is needed to serve the traffic needs in the future. Rigid pavement is an arrangement of pavement construction in which a concrete slab is used as the top layer, which is located on the foundation or directly above the subgrade (Bina Marga, 2003). The concept of the design of rigid pavement (cement concrete) using the Bina Marga method is planned for the configuration of the axle load which results in the greatest stress on the slab. The concept of pavement planning using the AASHTO method is that the thickness of the planned plate will increase according to the increase in equivalent traffic during the design life and vice versa, the thickness of the slab will decrease with the reduction of the equivalent traffic volume. Similarly, in the PCA method, the calculation obtained is almost the same as the Bina Marga method, but in determining the LHR of the vehicle, it only calculates the axle load of the truck. Planning of Pavement Concrete Plate Thickness using the Bina Marga, AASHTO, and PCA methods obtained respectively 30 cm, 32 cm, and 29 cm, there is a difference of 1-2 cm, this is due to differences in the basic concepts of each method.
