The major use of air-entraining admixtures is in the production of concrete pavings for roads and airfields where improved resistance to frost and de-icing salts is required. The Department of Transport specification for Road and Bridge Works specifies 4 /2% 114% air entrainment for the top 50 mm of pavement quality concrete.

Observations demonstrated that bonding of concrete slabs with polymer PM reduces vertical and horizontal deformations of them of about 50%, allowing for safe work of airfield pavements. It should be noticed that contractions joints deform horizontally of about 5 mm between winter and summer and similar value was measured in cases of vertical deformation. An example of 24 hours measurements of vertical displacements of airfield slab is presented in Fig. 16 (for original slab with bituminous filling and slab bonded with polymer PM). Comparison of vertical displacement shows that the use of polymer joints in contradiction to bituminous mass reduces warping deformations of the comers about two times, what is very advantageous in aspect of airfield exploitation.

PAs were developed during the 1960s in England, initially for airfield surface courses in order to eliminate rainwater, thus preventing aquaplaning. Successful full-scale trials on roads application led PA to be used in highway pavements as well (Brown 1973 Daines 1992 Nicholls 1997). Since then, other countries started to apply PA as a surfacing course. PA can successfully be laid over concrete surfaces (Nicholls 2001).
