Compaction Speci¿ Cation; Troubleshooting Guide - Belle Altrad PCX 350 Manuel De L'opérateur

GB
Various methods have been employed in the past to specify the compaction required for various applications. The factors to consider
are, material properties, layer thickness, pressure applied, vibration and number of passess. Greater
understanding of how compaction works has lead to new compaction speci¿ cations being introduced.
The most up to date speci¿ cation is part of the U.K.'s NRSWA (New Roads & Street Works Act). Civil Engineers are now adopting
these speci¿ cations to ensure good compaction for all site work.
NRSWA (HAUC speci¿ cation).
The speci¿ cation was compiled by HAUC (Highways Authorities & Utilities Committee).
The 'New Roads and Street Works Act 1991, set a new standard for road repairs and reinstatements in the UK. It covers materials,
methods, equipment and safety when carrying out reinstatements on roads and footways.
The reason for the act is to ensure repairs and reinstatements are carried out to a higher standard and ultimately last longer. This in
turn will reduce the need for costly remedial work and reduce traf¿ c delays.
There are two categories speci¿ ed for plate compactors.
1. 1400 to 1800kg/m²
These ¿ gures relate to the static pressure applied by the machine
NOTE: No standard single direction plate compactors comply with this minimum speci¿ cation. For highways work always use a 'Dual
Force' plate compactor.
DUAL FORCE
Belle Group studied the act then developed and patented equipment to enable contractors to comply with the act's requirements.
The NRSWA legislation requires that compaction equipment meets the minimum speci¿ cation. By purchasing an Belle Group 'Dual
Force' plate, you are immediately complying with this part of the act. To comply with the speci¿ cation and maintain surface tolerance,
Belle Group 'Dual Force' base plates are divided into two areas providing two stages of compaction.
Stage 1: The full base area compacts the material like a standard machine.
Stage 2: The base rises onto the 'Dual Force' section to give 3 to 4 times the compaction force of standard plates.

Troubleshooting Guide

Cause
No fuel.
Engine switched off.
Spark plug fouled.
Engine cold.
Engine À ooded.
Major Fault
Engine speed too slow.
Drive belt tension loose.
Air ¿ lter blocked.
Drive failure.
Vibrator failure.
Lack of lubrication.
Plate in direct contact with material.
Standard pad used on Dual Force plate.
Over compaction.
Layer thickness too deep.
Moisture content too high or too low.
Remedy
Open fuel tap.
Fill fuel tank.
Switch engine on.
Clean and reset plug gap.
Close choke.
Honda, open choke, fully open throttle, pull recoil starter
until engine ¿ res.
Hatz, move speed control to stop, pull recoil starter 5
times then repeat start procedure.
Contact Agent or Belle Group.
Set engine speed control to fast.
Adjust belt tension.
Clean or renew air ¿ lter.
Contact Agent or Belle Group.
Contact Agent or Belle Group.
Use a water spray system.
Use a paving pad.
Fit correct Dual Force Pad
Remove and relay.
Remove some of the material.
Remove material and adjust.
