    • A lime pellet for use in asphalt applications can include lime fines and an asphalt-compatible binder. The pellet is characterized as having a rigid structure with a dimension greater than about 1.5 mm and being compatible with a hot mix asphalt so as to dissolve in liquid asphalt. Optionally, the binder is characterized by having less than about 50% by weight of total binder being sulfur, or the pellet is characterized by having lime in an amount of at least 31% by weight, or being storage-stable and agglomeration resistant. The pellet is manufactured by mixing the lime fines with the asphalt-compatible binder and forming pellets therefrom. The pellets are useful for conditioning an end product of hot mix asphalt during the manufacture of such an asphalt. The method of conditioning includes providing the lime pellet, and mixing the lime pellet with a hot mix asphalt ingredient, wherein the ingredient is at least one of an aggregate or asphalt cement. Additionally, the lime pellets can be used for bonding a first asphalt layer with a second asphalt layer by being deposited therebetween.
    • 用于沥青应用的石灰颗粒可以包括石灰粉和沥青相容的粘合剂。 颗粒的特征在于具有尺寸大于约1.5mm的刚性结构,并且与热混沥青相容,以便溶解在液体沥青中。 任选地,粘合剂的特征在于具有小于约50重量%的总粘合剂为硫,或者颗粒的特征在于具有至少31重量%的量的石灰,或者是储存稳定的和防结块的。 颗粒通过将石灰细粉与沥青相容的粘合剂混合并由其形成颗粒来制造。 在制造这种沥青的过程中,颗粒可用于调理热拌沥青的最终产品。 调理方法包括提供石灰颗粒,并将石灰颗粒与热拌沥青成分混合,其中成分是聚集体或沥青胶泥中的至少一种。 此外,石灰颗粒可用于通过沉积第二沥青层与第二沥青层结合第一沥青层。

    • An extension ladder consisting of a lower ladder section and an upper ladder section secured to one another so that the upper ladder section can be extended relative to the lower ladder section using a ladder extension rope. Each ladder section has the same width and each has a pair of spaced stiles with rungs. A clutch member extends between the ladder sections and is movable between a locked position, for mounting the upper ladder section at a desired extension relative to the lower ladder section, and a released position. A clutch locking mechanism biases the clutch member into the locked position. The stiles of each ladder section has formations for securing the sections relative to one another, and enable the upper section to be extended and retracted in relation to the lower ladder section.
    • 由梯子下部和上梯形部分组成的延伸梯梯彼此固定,使得上梯子部分可以使用梯子伸长绳相对于下梯子部分延伸。 每个梯子部分具有相同的宽度,并且每个梯形部分具有一对具有梯级的间隔的立方体。 离合器构件在梯子部分之间延伸并且可在锁定位置之间移动,用于将上梯形部分相对于下梯形部分安装在期望的延伸部分,以及释放位置。 离合器锁定机构将离合器构件偏压到锁定位置。 每个梯子部分的台阶具有用于相对于彼此固定部分的结构,并且使得上部部分能够相对于下部梯形部分延伸和缩回。
