The difference b/w the prime generator & standby generator is that the prime generator is used for 24/7/365, while the standby generators are only used in emergency cases, if we used standby generators for more than 24 hours continuously, then it will be overheated for sure.
There is a substantial amount of misinformation concerning the function and proper use of prime. Prime is not glue-causing the base to adhere to the pavement is not its purpose. Prime's purpose is to protect the base from rain and light traffic, when the paving will be delayed.A prime coat is an application of an asphalt cutback or emulsified asphalt to a prepared base. The base can be either a sub grade or a base rock. Prime functions as a protector from rain for both types of bases. A primecoat should not be confused with a tack coat. Tack is an a adhesive for gluing two asphalt layers together.
Prime sealing coat shall be MC30 or MC70 complying with ASSHTO M82 or as directed by the Engineer and shall be applied to the prepared sub-base layer at a rate between 0.8 and 1.2kg/m2 and at a temperature between 60' C and 80' C. Tests shall be carried out on site to determine the rate of spread of the prime sealing coat material.
The algorithm is fairly straightforward. For any integer i greater than or equal to zero:i is non-prime if i is less than 2.otherwise, i is prime if i is 2.otherwise, i is non-prime if i is greater than 2 but is divisible by 2.otherwise, i is non-prime if it has any prime factors less than or equal to its square root.otherwise, i is prime.Step 4 is easier to implement by testing all odd divisors from 3 to the square root of i.
