Research studies carried out in some of the coldest climates in the USA have shown that permeable paving sub bases are not affected by cold temperatures. There have been no cases of frost heave damaging Hydropave Permeable Pavements in the UK. When the correct aggregates are used in the sub base, they have a high void space ratio which means they drain quickly.
