Analysis of productivity and the need for heavy equipment on grade B aggregate foundation layers work (case study: Pekan Gedang road section, Batang Asai – Muaro Talang District, Sarolangun)

Abstract

Grade B aggregate foundation layers are part of the road foundation that is located between subgrade and grade A foundation layers. The function of grade B aggregate foundation layers is to minimize the spread of loads to the subgrade. Road infrastructure is one of the factors that support an area development. Road improvements aimed to improve the social economy and open access to isolated areas of considerable potential for the development of natural resources. This research analyses productivity and the need for 5 types of heavy equipment on grade B aggregate foundation layers work (case study: Pekan Gedang road section, Batang Asai – Muaro Talang District, Sarolangun). Noted that heavy equipment specifications were used in project site same as the planned. The results showed that based on time schedule and project volume in this research can be completed properly and on time if using 5 units of dump trucks and 1 unit each for wheel loader, vibratory roller, motor grader and water tank truck, with productivity for wheel loader is 125.42 m3, dump truck is 2.69 m3, vibratory roller is 87.15 m3, motor grader is 57.24 m3 and water tank truck is 71.14 m3.
