Installing pavement surfaces entails a series of processes and procedures in order to come up with a firm road pavement course. Adequate preparation of aggregate stones and hot mix has to be done. Some of the asphalt paving preparations that need to be carried out include the construction of a firm base. One may either decide to lay a perfectly new course or install an asphaltic pathway over a pr- existing driveway.
If the existing driveway is in a good state and without fault, there is no need of putting up a new pavement. To put the pavement, you use a hot mixture of asphalt on the road course. The most important section of the asphalt course way is the base. It is the base that determines the lifespan and the durability of the paving.
It is the preparation step that has a bearing for the lifespan of a pavement. All unusable materials should be excavated and removed from the job site. Items that should be discarded from the site before the commencement of job include loam, clumps, clay as well as other soft material in the ground.
For a strong and compact finish to be obtained, the preparation stage should be completed satisfactorily. It is then that compaction can be undertaken. Compaction ensures that asphaltic compounds stick together so that no weather or external conditions will split the road surfaces giving forth cracks and potholes.
Once the surface is properly prepared, compaction and finishing procedures can be undertaken. Without proper compaction, asphalts may not be held together and endure many seasons. After laying the asphaltic material, the surface should be rolled with a vibratory drum roller for a smooth and strong finish.
As long as the degree of depravity is high, the asphaltic material will continue to deteriorate rapidly. Some of these natural conditions include excessive heat and harmful solar energy rays. Heavy trucks on the roads also pose a danger to the pavings by weakening the compaction of hot mix aggregate leading to the formation of potholes. The cracks in the asphalt are good inlets of water into the base floor.
Presence of inappropriate drainage systems may also lead to flooding when heavy downpours fall on the surface. This may loosen the asphaltic compaction. Petroleum carrying trucks may spill oil on the way and when such oil falls on the asphaltic blacktop, it may soften it thereby leading to the dilapidation of the pavements.
It is from cracks that potholes are formed. When these potholes merge, they cause a pavement to lose its shape and resemble a dusty footpath. This is what happens with alligator cracks. Repairing such roads is usually a tall order. However, pothole formation can be avoided if only the roads are maintained properly.
