Aftercare of newly laid tarmac driveways

As in all situations, prevention is better than cure. Treat all new tarmac or asphalt surfacing with great care, particularly when the surface is warm. The most frequent causes of damage to newly laid asphalt surfaces are listed below.

New tarmac surfacing when first laid

When asphalt / tarmac is first laid, the finished surface will have a glossy black appearance. Within several weeks, dependant upon use, the glossiness will fade as the surface is exposed to the elements. Within 6 months to a year the tarmac colouring will lighten a few degrees in shade as the binder near to the top of the tarmac surface is exposed to sunlight.

Staining of newly laid tarmac surfaces

Once your new tarmac surfacing is laid there might appear to be staining and/or brown marks in some areas once the rolling process has been completed. This staining is caused by the water used to prevent the roller from sticking to the new surface and will usually disappear after just a few days and does not effect the performance at all of the surface.

Avoiding damage to newly laid asphalt surfacing

Newly laid tarmac is at greater risk to damage in its early life before the surface hardens over time. This risk is increased particularly in the summer months and the driveway has just been installed when temperatures are at their highest. Damage can be caused by the use of ladders, standing vehicles such as caravans, motorbike stands etc. Although any damage can be repaired, often the repaired areas can be obvious and spoil the overall appearance of the surface. This damage can be avoided by the use of boards under ladder feet or caravan / bike stands for the first few weeks.

Contamination of a newly laid tarmac surface

The vast majority of new tarmac will soften when contaminated with oil, petrol, diesel, paraffin and the extent of the damage caused will be determined by the amount of contaminant spilled and how long it is left before being treated. It is advisable to immediately soak up any oil based spillage using sawdust, dry sand or absorbent paper and remove once the spillage has been absorbed. For small oil stains from vehicles brush the affected area using a soft broom and a soapy solution or non-solvent based cleaning agent. This will ensure that the oil can cause no long term damage to the structure of the asphalt but staining will remain. Remember to always act fast to avoid long term damage or heavy staining.
