Anticipating the arrival of the heat and low humidity environment to multiply the effect of fine suspended, and have been conducting several test sections in different traffic conditions to evaluate their performance and durability.

Were tested dosages of 0.6 to 1.0 L / m2, with the optimum performance for dust control is at low doses and releasable traffic almost immediately and are not accumulation zones emulsion. For all these tests has been carried out prior sweep the surface and has cared moisture in it was low for better performance of the emulsion.

In one of the test sections was used as 2-6 mm gravillín immediate release protection traffic without the gravillín interfere with curing or penetration depth since the absorption rate at the base is very fast. With this technique it is possible to urban jobs without cutting the road in no time.

After heavy rains last week some edges of the test sections were eroded by rain which allowed us to check the depth of action of the PRINT 50 and enclosed in photographs.

We estimate that the lifetime of the dust treatment performed with this emulsion, due to the depths reached, must be above 12 months.
