How does Trimble 3D technology improve the precision of asphalt and concrete laying
Trimble 3D technology significantly enhances the precision of asphalt and concrete laying through automated control, data collaboration and millimeter-level operation. The specific mechanisms are as follows:
1. Millimeter-level automated paving control
The Trimble PCS900 3D paving control system is adopted to directly read the design data and automatically lay asphalt/concrete with an accuracy of up to 5 mm (better than the 10 mm design requirement), completely avoiding the problem of uneven thickness caused by manual wire pulling positioning. For instance, in the airport project in Peru, the three layers of asphalt on the runway were laid to form seamless hot joints, eliminating the risk of water seepage. Similarly, the Shenzhen Yanguang East Interchange Project applied this technology to strictly control the thickness difference of asphalt within 5 millimeters, ensuring a smooth and flat road surface.
The motor grader is equipped with the Trimble GCS900 slope control system , which precisely regulates the slope and thickness of the base layer, with tolerances meeting strict standards, significantly reducing the need for rework. In the Chunfeng Road Tunnel project, the system achieved a standard deviation of only 0.8 millimeters for the flatness of the asphalt leveling layer, far exceeding the expected acceptance value.
Ii. Stable Milling and depth Control in Harsh Environments
The milling machine integrates a Trimble active tracking target and a total station (such as the SPS930 model), which can automatically maintain an accurate milling depth (for example, precisely stripping a 4-6 cm concrete layer) under conditions of dust, rain, fog or night, avoiding manual measurement deviations. The Huangmugang Comprehensive Transportation Hub Project has optimized the manhole cover laying through this technology, achieving automatic adjustment of height differences and ensuring the consistency of the overall paving surface.
Iii. Data collaboration closed-loop ensures construction consistency
Based on the Trimble Connect cloud platform , centimeter-level data collected by laser scanners and drones and 2,700 active BIM models are synchronized in real time to ensure that on-site equipment always uses the latest design version and eliminate errors in the transmission of paper drawings.
Trimble WorksManager system transmits design data directly to construction machinery and feeds back completion data in real time for automatic comparison (such as generating flatness reports), achieving "zero blind spot" acceptance and replacing traditional manual spot checks.
Overall effect : In large-scale infrastructure projects such as airport runways and tunnel engineering, this technology systematically enhances the laying accuracy to the millimeter level, reduces material waste and rework rates, and promotes the industry's transformation towards digital construction.
