HOME ROAD SEALING NATURAL STONES DREANED RESIN FLOORS CONTACTS Login Hot road sealing with bituminous rubber mastic The sealing of cracks with hot bituminous mastic represents one of the most effective preventive maintenance interventions of pavements since it allows to block the passage of water in the deep layers of the road structure and to avoid aggravation of cracks with the consequent formation of reticular cracks and subsequently of holes. Each flooring shows the first signs of deterioration already after the first 2-3 years of life. Being able to block or slow down the degradation with modest cost interventions allows to extend the useful life of the pavement itself, postponing or even eliminating future resurfacing interventions, with an enormous benefit, also from a financial point of view, for those who manage infrastructure. The intervention with hot bituminous mastic allows the reopening to traffic after only 2/3 minutes from the laying, minimizing the inconvenience to traffic. For particular situations the machine is equipped to carry out the intervention even during the night hours. The mastic is applied by fusion and must be carried out using the special stirred and thermo-controlled melter. Operating / casting temperature: + 160 ° C. Critical temperature: max 180 ° C for 2 hours. PROPERTY OF MASTIC High elastic return; Excellent surface hardness; Excellent adhesion to the walls of the joint; Does not drip at high temperatures (+/- 60 ° C). PREPARATION OF THE LAYING SURFACE The joint or lesion must be clean, dry and free from impurities. CONDITIONS OF LAYING-USE The sealing intervention can only be carried out in the dry and not cold season (operating temperatures not lower than 12 ° and absolute absence of atmospheric precipitation). It is therefore not recommended to operate in humid and / or cold seasons. MERGER AND APPLICATION The mastic is applied by fusion and must be carried out using the special stirred and thermo-controlled melter. Operating / casting temperature: + 160 ° C. Critical temperature: max 180 ° C for 2 hours. Maintenance temperature in the boiler: 150/170 ° C _ The mastic in loaves must be heated to a temperature between 150 and 170 ° C. Too low temperatures can lead to a partial melting of the bread, resulting in poor modeling of the seal inside the crack. Conversely, temperatures that are too high damage the behavior of the mastic already in the laying phase and its performance over time. It is therefore essential that the melter is equipped with a temperature control and with a flame block for temperatures greater than about 190 °. Maximum time at holding temperature: 6/8 hours.
