Pearce opts for BK paver on M4

Wiltshire-based G Pearce Civil Engineering - involved in the paving contract for the new M4 Services (westbound) near Reading - has been using a Blaw-Knox BK-191 paver with Omniscreed V to tackle the work.

The œ750,00 contract called for the laying of 20,000t of bituminous and asphalt materials.

Paver features include Blaw-Kontrol II - an accurate, microprocessor-based control system that automatically maintains the elevation of one side of the screed with respect to a reference surface (grade), while maintaining the elevation of opposite side of the screed in relation to the first slope.

Surfacing manager for G Pearce, Steve Tregelles, said: 'The choice of paver was a difficult one for us to make. In the end, the Blaw-Knox specification best suited our needs. The BK-191 is now our main workhorse, replacing a BK-170 paver.'

Pearce's task has involved laying the road base, base courses and a variety of wearing courses for the roads and parking areas.

A wearing course of asphalt with pre-coated chippings was specified for high stress areas, such as the access roads and filling station.

The hydraulically extendible Omniscreed V paves widths from 2.5m up to 4.75m.

Pearce began work at the beginning of November. The Westbound services are due to open by Easter this year.
