Transcription

1 elastic pavements ltd Manufacturer of highly specialist equipment Falling Weight Deflectometer Model ASTEC G The device is used to measure the vertical deflection response of a surface to an impulse load. It applies a dynamic load that simulates the loading of a moving wheel. The load is produced by dropping a large weight, and transmitted to the pavement through a circular load plate. FWD Trailer mounted version Brief characteristics: Falling Weight Deflectometer The FWD produced by our company is mounted on a dual-axle trailer of overall weight up to 1350kg. The load range is 0-120kN. The number of geophones can be configured according to specific Client's requirements. The maximum number of geophones is 15 (standard 9). The device is equipped with ambient and ground temperature sensors (infrared light). The device is operated automatically by the built-in and appropriately programmed driver, controlling the work of a set of hydraulic cylinders. The processing software is supplied with the English-language version. It is also possible to adapt the software to any language. Once we receive the official order, the delivery date is within 90 days.

6 Manufacturer of highly specialist equipment Dynamometer Trailer SRT (Skid Resistance Tester) Model SRT6001 The device is intended for measurement of the coefficient of friction. SRT - Skid Resistance Tester Model SRT6001 Brief characteristics: Skid resistance Tester The device is intended to calculate surface anti-skid properties. The measurement involves performing emergency stops in a test vehicle with a locked wheel while watering the pavement surface with 0.5 l/m2. It measures the coefficient of friction between the tyre and the road surface. A very important issue is the adjustment of a car provided by a Client, which will serve as a tow vehicle for the device. The car should be capable of transporting a water tank with a capacity of at least 300 litres (preferably - larger). Our standard offer does not include the towing vehicle. However, it includes all activities related to the adjustment of the tow vehicle provided by the Client to the device (water tank installation, electrical installation, integration with high pressure pump and other minor alterations of the vehicle).
