Why do you surface dress/micro asphalt a road?
Surface treatments can extend the life of a road surface by up to 10 years and is a cost effective and quick process. This type of work is suitable for roads in a generally good condition. Usually a road will be patched repaired ahead of the surface treatment. Both treatments are used in urban and rural areas.
The treatments provide the following benefits to a road:
- Skid resistance – the application of either material will rejuvenate the road’s skid resistance.
- Sealant – the process seals cracks and joints of a reasonable width and prevents water entering the roads construction. Water which enters in this way is quite often the cause of potholes during the cold months of the year.
- Uniformity – by covering the whole road with one surface treatment, a degree of uniformity to the appearance of the road will be achieved on a road which has been continuously patched.
- Economy – the cost of Micro Asphalt, per square metre of the road is approx. £8. The cost of Surface Dressing per square metre is £4. The cost of removing the top 100mm of a road, surface and replacing it with a new tarmac surface is in the region of £25 per square metre. Sometimes a road will have deteriorated to much to respond favourably to a surface treatment and a Rolls Royce £25 sqm job is the only answer. However, if the road is at the beginning of its decline and only just showing signs of tiredness and wear then a surface treatment will halt the decay and actually extend its working life by up to 10 years.
Why has the surface dressing/micro asphalt work been delayed?
Surface dressing cannot be laid in the road, on a wet surface or it is too hot. Neither treatment can be laid in cold temperatures. With the UK weather being fairly unpredictable, it is not unusual for delays to occur.
Can we get access to our property whilst the works are taking place?
We carry out surface dressing and micro asphalt work under a road closure. It is difficult for us to provide safe vehicular access in and out of the site, so ideally we ask residents who need access within working times to park outside of our working area. The sooner we know of an access request, the more likely we will be able to accommodate it. We try to give access to vehicles as far as is safe and practicable, but delays will be inevitable.
Why are there so many loose chippings?
Both surface treatments shed their chippings for several days after they have been applied. We have a road sweeping regime over the following week to try and retrieve potential skid-risks. We also have a 20mph advisory speed limit on all surface dressing sites. Travelling at this speed dramatically reduces the amount of chipping flick from vehicles.
Why have you left the road unfinished?
The aftercare regime required for each process means that we do not totally finish the work in one visit. Sweeping, lining, reflective studs and manhole/gully adjustments all take place at a later date.
My car has been moved/is missing
During roadworks, if parking has been suspended, it is possible your car may have been towed. Sometimes the vehicle is relocated onto the next road. If you think we may have moved your vehicle then please contact us so we can advise you further.
