DPWH applies new technology on road construction in Tarlac By Rosa Bianca Pamintuan TARLAC CITY, July 5 (PIA) -- Department of Public Works and Highways (DPWH) Tarlac 1st District Engineering Office (DEO) recently applied the new technology on road construction using the geotextile materials integrated in its asphalt overlay projects. The project is a 441-lineal meter of asphalt overlay from KO151+000 – KO151+441 along Romulo Highway in the municipality of Sta. Ignacia. “Such undertaking is under the Pilot Road Research Project which involves the construction of the First Small Scale Pilot Trial on use of Paving Fabric in Longitudinal Weakened Plane Joints. The Bureau of Research and Standard guided our engineers on the proper method of application,” District Engineer Benjie Lopez shared. The use of geotextile material was to preempt the occurrence of reflection cracks on the road pavement. Prior to the actual integration of the geotextile, pothole patching and crack sealing were done. A leveling course of 0.025 meter of asphalt overlay ready mix equivalent to one inch in thickness was laid and applied with bituminous tack coat (CSS1 0.7-1.0 li/sq.m.) primer. The geotextile material was then laid on the surface and flattened using power brush to avoid air pocket on the surface. “We will do constant monitoring to determine how the newly paved road will respond to the average daily traffic of vehicles. If it is sturdy and responsive to the daily motoring grind, another milestone in road construction is achieved. It will mean lesser cost on the part of the government in its construction business as it will avoid early and costly rehabilitation and reduce transport cost of the road users,” Lopez added. Last year, Bulacan 1st DEO experimented on the same paving fabric integration in their asphalt-overlay project along Manila North Road in Malolos City.
