Abstract: The present invention relates to a leaf spring cushion for people who have a knee joint that is worn out and suffer from knee pain, and is to replace a function of cartilage in the knee joint so as to relieve knee pain and back pain. In the meantime, many people have made a lot of effort to make shoes with a spring cushion device. However, efforts have been made to make the shoes with a linear spring. In operation, the linear spring is irregular folded, and in particular, low-height shoes cannot be made using the linear spring. Due to such disadvantages, it has been failed to make spring cushion shoes. As a result, even when many people suffer from pain with knee cartilage that is worn out, there is no solution for the people other than a surgery. The present invention is devised to solve the problems. To this end, a leaf spring that works consistently is developed such that a low-heeled shoe can be made using the leaf spring. In particular, the spring works consistently so as to prevent a person who wears the shoe from falling. A protruding wing leaf spring does not generate noise during operation, and exhibits an excellent cushion feel. In addition, even when the heel of the shoe is worn out, the shoe insole can be used for a long time, thereby being helpful to all the households. The present invention can help a user be free of knee pain and back pain for a lifetime even without a surgery, and thus can be a great help in the history of mankind and can be very useful.

Abstract: Disclosed is an asphalt manufacturing method combining continuous mixing and forced mixing, which belongs to the concrete processing technology filed. According to the present invention, the asphalt manufacturing method comprises the following steps: heating cold aggregate to acquire hot aggregate and acquiring a reclaimed material from a milling material through a heat treated hot mix and/or a cold mix; acquiring a premix by mixing the hot aggregate, the reclaimed material, a powder material, and asphalt; temporarily storing the premix in a premix storage bin, introducing the same into a forced mixing tank to be mixed with materials, and inputting and temporarily storing an acquired finished product material in a finished product storage bin; and loading the finished product material in a storage tank of a finished product material transport vehicle in a finished product material loading area. Secondary incineration is performed by introducing generated asphalt smoke and water vapor into a drying cylinder, the collected dust enters a waste absorption and purification apparatus to be processed through waste purification treatment, and at the same time, the collected smoke and air are introduced into a burner area to be used as an oxidizing gas. Accordingly, the milling material is prevented from being directly burned by fire, soft aggregating is prevented from being smoothly premixed with the reclaimed material, the powder material, and the asphalt, thereby increasing mixing efficiency. Moreover, the asphalt smoke is prevented from leaking to the outside to be used as thermal energy, thereby saving energy and being eco-friendly.
